Thank you so much for playing! I'm glad you enjoyed it. The cat going pstpstpst is one of my favorite parts.
I'll take a look at the collisions. It was about 3am when I finished and submitted. I'm sure I missed something. I do know when I've playtested few times that all areas are accessible. Until I check out the collisions I suggest to keep trying. Follow the boundaries around the map.
Keep looking for the sword. I believe in you!
